Answer:
36
Step-by-step explanation:
EF = is 1/3 of 15
Since the triangles are similar, then the perimeters are similar.
The perimeter of EDF is 12
The perimeter of ABC should be 3 times as large.
3*12 = 36
The perimeter of ABC = 36
Similarly to the last graph that decreased, this one increases, so you have to see where the line points upwards into the right top corner
CD
No. You can’t add the two lower numbers up to make the bigger number making them not a triangle.
Answer:
Water (one oxygen atom bonded to two hydrogen atoms)
Step-by-step explanation:
The chemical formula for water is H²O. The H is the chemical symbol for Hydrogen and O is the chemical symbol for Oxygen. The 2 is a subscript which represents how many atoms of a certain element are in a molecule. In this case, the subscript ² comes after H, indicating that there are two Hydrogen atoms inside water. There is no subscript after O, meaning there is only one Oxygen atom. Therefore, there are two Hydrogen atoms and one Oxygen atom that bond to form water. Hope this helps :))
Answer:
Tuesday : Total = 30 : 72 = 5 : 12
Step-by-step explanation:
Monday: 42 miles
Tuesday: 42 - 12 = 30 miles
Monday + Tuesday: 42 + 30 = 72 miles
Tuesday : Total = 30 : 72 = 5 : 12
